iOS 符号化Crash崩溃日记 查找崩溃日志 防崩溃

一、崩溃符号化

1.桌面新生成一个crash的文件夹


image.png

2.将crash的txt的文件复制到上边的文件夹中并命名crash.txt


image.png

3.Xcode-Window-Organize找到要检查的对应Archives找到App－右击－Show in Finder
（1）右击 .xcarchive 文件-显示包内容。

（2）复制dSYMs文件夹下的 **.app.dSYM 文件和 Products->Applications文件夹下的 app文件放入上边的crash文件并命名

4.打开终端输入以下命令： 
find /Applications/Xcode.app -name symbolicatecrash -type f
//我得到的目录：
/Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash

5.用命令生成symbolicatecrash并拷贝到桌面的crash文件夹里面，与.app和.app.dSYM放一起（如下图）

cp /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash /Users/***/Desktop/crash
image.png

6.cd 进入crash目录
（1）生成Test_symbol.crash

//执行此命令（记得留好空格）
./symbolicatecrash /Users/***/Desktop/crash/crash.txt /Users/***/Desktop/crash/crash.app.dSYM > Test_symbol.crash

（2）终端执行完成以后，crash文件夹会有一个Test_symbol.crash，通过这个文件可以查看导致程序崩溃的原因】

通过Test_symbol.crash这个文件可以查看导致程序崩溃的原因

至此符号化完成

可能碰到的问题：

1.Error: "DEVELOPER_DIR" is not defined at ./symbolicatecrash line 69.

//输入此命令
export DEVELOPER_DIR="/Applications/XCode.app/Contents/Developer"

二、查找崩溃日志

1.Xcode中崩溃日志

选中Xcode中的Window->Orgnizer

2.手机中的崩溃日志
设置->隐私->分析与改进->分析数据->选择对应app查看（exception）
3.接入第三方SDK（Bugly等SDK不赘述）

三、防止APP崩溃、闪退

1.使用try catch
image.png
@try{
//1:抛出异常的代码
//2:代码
} @catch(NSException *exception){
//3:代码
//4:抛出异常
} @finally{
//5:代码
}

2.使用runtime
创建一个新的文件
(1).h文件
